2. CONTINGENT VALUE RIGHTS

2.1. CVRs. The CVRs represent the rights of Holders to receive contingent cash payments pursuant to the Merger Agreement and this Agreement. The initial Holders shall be determined pursuant to the terms of the Merger Agreement and this Agreement, and a list of the initial Holders shall be furnished to the Rights Agent by or on behalf of Parent in accordance with Section 4.1 hereof. Each CVR represents the right of a Holder to receive the Milestone Payments in accordance with this Agreement.

2.2. Non-transferable. The CVRs may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than through a Permitted Transfer. Any such sale, assignment, transfer, pledge, encumbrance or disposal that is not a Permitted Transfer shall be null and void.

2.3. No Certificate; Registration; Registration of Transfer; Change of Address.

(a) The CVRs shall not be evidenced by a certificate or other instrument.

(b) The Rights Agent shall keep a register (the “CVR Register”) for the purpose of registering CVRs and transfers of CVRs as herein provided. The CVR Register will initially show one position for Cede & Co. representing all of the CVRs that are issued to the holders of Shares held by DTC on behalf of the street holders of the Shares. The Rights Agent will have no responsibility whatsoever directly to the street name holders or DTC participants with respect to transfers of CVRs. With respect to any payments to be made under Section 2.4 below, the Rights Agent will accomplish the payment to any former street name holders of the Shares by sending a lump sum payment to DTC. The Rights Agent will have no responsibilities whatsoever with regard to the distribution of payments by DTC to such street name holders. In the case of CVRs to be received by the holders of In-the-Money Options and Company Stock Rights pursuant to the Merger Agreement, such CVRs shall initially be registered in the name and address of the holder of such In-the-Money Options and Company Stock Rights as set forth in the records of the Company at the Effective Time and in a denomination equal to the number of Shares subject to such In-the-Money Options and Company Stock Rights cancelled in connection with the Merger.

(c) Subject to the restrictions on transferability set forth in Section 2.2, every request made to transfer a CVR must be in writing and accompanied by a written instrument of transfer and other documentation reasonably requested by the Rights Agent in form reasonably satisfactory to the Rights Agent pursuant to its guidelines, duly executed by the Holder thereof, the Holder’s attorney duly authorized in writing, the Holder’s personal representative or the Holder’s survivor, as applicable, and setting forth in reasonable detail the circumstances relating to the transfer. Upon receipt of such written notice, the Rights Agent shall, subject to its reasonable determination that the transfer instrument is in proper form, notify Parent that it has received such written notice. Upon receipt of such notice from the Rights Agent, Parent shall in good faith reasonably determine whether the transfer otherwise complies with the other terms and conditions of this Agreement (including the provisions of Section 2.2), and if Parent so reasonably determines that it does so comply, Parent shall instruct the Rights Agent in writing to register the transfer of the CVRs in the CVR Register and notify Parent of the same. No service charge shall be made for any registration of transfer of a CVR, but Parent and the Rights Agent may require payment from the applicable Holder of a sum sufficient to cover any stamp or other Tax or charge that is imposed in connection with any such registration of transfer. The Rights Agent shall have no duty or obligation to take any action under any section of this Agreement that requires the payment of applicable Taxes or charges unless and until the Rights Agent is satisfied that all such Taxes or charges have been paid. All duly transferred CVRs registered in the CVR Register shall be the valid obligations of Parent and shall entitle the transferee to the same benefits and rights under this Agreement as those held immediately prior to the transfer by the transferor. No transfer of a CVR shall be valid unless and until registered in the CVR Register.

(d) A Holder may make a written request to the Rights Agent to change such Holder’s address of record in the CVR Register. The written request must be duly executed by the Holder. Upon receipt of such written request, the Rights Agent is hereby authorized to, and shall promptly, record the change of address in the CVR Register.

2.4. Payment Procedures.

(a) On each Milestone Payment Date, Parent will deliver to the Rights Agent a certificate (an “Entitlement Certificate”) certifying that either (i) the Holders are entitled to receive the applicable Milestone Payment (and setting forth the calculation of such Milestone Payment) and/or (ii) a Transaction Milestone has been achieved but no Transaction Milestone Amount is payable because the applicable Transaction Milestone Amount is zero (and setting forth the calculation showing the calculation of the Transaction Milestone Amount for the applicable Transaction Milestone). If the Entitlement Certificate certifies that the Holders are entitled to receive a Milestone Payment, then, concurrent with the delivery of such Entitlement Certificate, Parent will deliver to the Rights Agent cash, by wire transfer of immediately available funds to an account specified by the Rights Agent, equal to the aggregate amount necessary to pay the applicable Milestone Payment to all Holders pursuant to Section 4.2, along with any letter of instruction reasonably required by the Rights Agent.

(b) The Rights Agent shall promptly, and in any event within ten (10) Business Days of receipt of an Entitlement Certificate and, if applicable, cash, by wire transfer of immediately available funds, equal to the aggregate amount necessary to pay the Milestone Payment to all Holders pursuant to Section 4.2 as well as any letter of instruction reasonably required by the Rights Agent, send each Holder at its registered address a copy of such Entitlement Certificate, including, if applicable, detail regarding the ability of a Holder or Holders to dispute or contest such determination that no Milestone Payment is payable pursuant to this Agreement. If a Milestone Payment is payable to the Holders, then at the time the Rights Agent sends a copy of the Entitlement Certificate to the Holders, the Rights Agent shall also pay the Milestone Payment to each of the Holders in accordance with the corresponding letter of instruction (i) by check mailed to the address of such Holder reflected in the CVR Register as of 5:00 p.m. New York City time on the date of the Entitlement Certificate or (ii) with respect to any such Holder that is due an amount in excess of $100,000 in the aggregate who has provided the Rights Agent wiring instructions in writing as of the close of business on the date of the Entitlement Certificate, by wire transfer of immediately available funds to the account specified on such instructions.

(c) Each of Parent, its Affiliates and the Rights Agent shall be entitled to deduct or withhold from any payments made pursuant to this Agreement such amounts as are required to be deducted or withheld therefrom under the Code, the U.S. Treasury Regulations thereunder, or any other applicable Tax Law, as may be reasonably determined by Parent, its Affiliate or the Rights Agent. With respect to Equity Award CVRs, any such withholding may be made, or caused to be made, by Parent through the Company’s or an Affiliate’s payroll system or any successor payroll system. Prior to making any Tax withholdings or causing any Tax withholdings to be made with respect to any Holder (other than payroll withholding and reporting on the Covered Milestone Payments (as hereinafter defined)), the Rights Agent shall solicit from such Holder an IRS Form W-9, an appropriate IRS Form W-8 or other applicable Tax form within a reasonable amount of time in order to provide the opportunity for the Holder to provide such Tax forms to avoid or reduce such withholding amounts. The Rights Agent shall properly and timely remit, or cause to be properly and timely remitted, any amounts it withholds in respect of Taxes to the appropriate Governmental Entity. To the extent any amounts are deducted or withheld and properly and timely remitted to the appropriate Governmental Entity, such amounts shall be treated for all purposes under this Agreement and the Merger Agreement as having been paid to the Holder to whom such amounts would otherwise have been paid, and, to the extent required by applicable Law, Parent shall deliver (or shall cause the Rights Agent to deliver) to the Holder to whom such amounts would otherwise have been paid an Internal Revenue Service Form 1099, an Internal Revenue Service Form W-2 or other reasonably acceptable evidence of such withholding. To the extent amounts are deducted or withheld from the Covered Milestone Payments, the Rights Agent shall, as soon as reasonably practicable, deliver such amounts to Parent for the purposes of remitting such amounts to the IRS. In no event shall the Rights Agent have any duty, obligation or responsibility for wage or IRS Form W-2 reporting with respect to Milestone Payments (including Covered Milestone Payments) made to the Holders.

(d) If any funds delivered to the Rights Agent for payment to Holders as Milestone Payments remain undistributed to the Holders on the twelve (12) month anniversary of the applicable Milestone Payment Date, Parent shall be entitled to require the Rights Agent to deliver to Parent or its designee any funds which had been made available to the Rights Agent in connection with such Milestone Payment and not disbursed to the Holders (including, all interest and other income received by the Rights Agent in respect of all funds made available to it), and, thereafter, such Holders shall be entitled to look to Parent (subject to abandoned property, escheat and other similar Laws) only as general creditors thereof with respect to the Milestone Payments that may be payable.

(e) Neither Parent, the Rights Agent nor any of their Affiliates shall be liable to any Holder for any Milestone Payments delivered to a public official pursuant to any abandoned property, escheat or other similar Laws. Any amounts remaining unclaimed by such Holders at such time at which such amounts would otherwise escheat to or become property of any Governmental Entity shall become, to the extent permitted by applicable Laws, the property of Parent or its designee, free and clear of all claims or interest of any Person previously entitled thereto. In addition to and not in limitation of any other indemnity obligation herein, Parent agrees to indemnify and hold harmless the Rights Agent with respect to any liability, penalty, cost or expense the Rights Agent may incur or be subject to in connection with transferring such property to Parent. The indemnification provided by this Section 2.4(e) shall survive the resignation, replacement or removal of the Rights Agent and the termination of this Agreement.

(f) The parties hereto intend to treat, for all U.S. federal and applicable state and local income Tax purposes, except to the extent any portion of any Milestone Payment is required to be treated as imputed interest pursuant to applicable Law, (i) the CVRs received with respect to the Shares, other than the Equity Award CVRs, pursuant to the Merger Agreement as additional consideration paid at the Effective Time for the Shares in connection with the Offer or the Merger, as the case maybe, pursuant to the Merger Agreement, (ii) any Milestone Payments received in respect of such CVRs as amounts realized on the disposition of the applicable CVRs, and (iii) any Milestone Payments paid in respect of each Equity Award CVR (the “Covered Milestone Payments”), as compensation in the year in which the Milestone Payment is made.

(g) Beginning in the Calendar Year in which the First Commercial Sale occurs, if a Net Revenue Milestone is not achieved during a Calendar Year, then on or before the date that is sixty (60) days after the expiration of each such Calendar Year period, Parent shall deliver to the Rights Agent a certificate certifying that such Net Revenue Milestone has not occurred, accompanied by a statement setting forth, in reasonable detail, a calculation of Annual Global Net Revenue for the applicable period (each, a “Net Revenue Milestone Non-Achievement Certificate”). The Rights Agent shall promptly, and in any event within ten (10) Business Days of receipt of a Net Revenue Milestone Non-Achievement Certificate, send each Holder at its registered address a copy of such Net Revenue Milestone Non-Achievement Certificate, including detail regarding the ability of a Holder or Holders to dispute or contest such determination of non-achievement of a Milestone pursuant to this Agreement.

(h) All funds received by the Rights Agent under this Agreement that are to be distributed or applied by the Rights Agent in the performance of services hereunder (the “Funds”) shall be held by the Rights Agent as agent for Parent and deposited in one or more bank accounts to be maintained by the Rights Agent in its name as agent for Parent. Until paid pursuant to the terms of this Agreement, the Rights Agent will hold the Funds through such accounts in: deposit accounts of commercial banks with Tier 1 capital exceeding $1 billion or with an average rating above investment grade by S&P (LT Local Issuer Credit Rating), Moody’s (Long Term Rating) and Fitch Ratings, Inc. (LT Issuer Default Rating) (each as reported by Bloomberg Finance L.P.). The Rights Agent shall have no responsibility or liability for any diminution of the Funds that may result from any deposit made by the Rights Agent in accordance with this paragraph, including any losses resulting from a default by any bank, financial institution or other third party. The Rights Agent may from time to time receive interest, dividends or other earnings in connection with such deposits. The Rights Agent shall not be obligated to pay such interest, dividends or earnings to Parent, any Holder or any other Person, unless there is a diminution of the Funds due to a deposit or investment made by the Rights Agent, in which case, the Rights Agent agrees that such interest, dividends or earnings shall accrue to the benefit of Parent to the extent of such diminution of the Funds.

2.5. No Voting, Dividends or Interest; No Equity or Ownership Interest.

(a) The CVRs shall not have any voting or dividend rights, and interest shall not accrue on any amounts payable on the CVRs to any Holder.

(b) The CVRs shall not represent any equity or ownership interest in Parent, the Company or in any constituent company to the Merger or any of their respective Subsidiaries or Affiliates.

2.6. Ability to Abandon CVR. A Holder may at any time, at such Holder’s option, abandon all of such Holder’s remaining rights in a CVR by transferring such CVR to Parent or any of its Affiliates without consideration therefor. Nothing in this Agreement shall prohibit Parent or any of its Affiliates from offering to acquire or acquiring any CVRs for consideration from the Holders, in private transactions or otherwise, in its sole discretion. Any CVRs acquired by Parent or any of its Affiliates shall be automatically deemed extinguished and no longer outstanding for purposes of the definition of Acting Holders.

2.7. No Obligations of Parent. (a) Parent and its Affiliates shall have the power and right to control all aspects of their businesses and operations (and all of their assets and products), and subject to its compliance with the terms of this Agreement, Parent and its Affiliates may exercise or refrain from exercising such power and right as it may deem appropriate and in the best overall interests of Parent and its Affiliates and its and their equityholders, rather than the interest of the Holders, (b) subject to Section 4.6, none of Parent or any of its Affiliates shall have any obligation to own, operate, use, sell, transfer, convey, license, develop, commercialize or otherwise exploit in any particular manner any of their business or operations (or any of their assets or products) or to negotiate or enter into any agreement, including in order to obtain, maximize or expedite the completion of any Milestone, and (c) none of Parent or any of its Affiliates (or any directors, officers, employees or other representatives of the foregoing) owes any fiduciary duty or similar duty to any Holder in respect of the CVRs.

3. THE RIGHTS AGENT

3.1. Certain Duties and Responsibilities. Parent hereby appoints the Rights Agent to act as rights agent for Parent in accordance with the express terms and conditions set forth in this Agreement (and no implied terms and conditions), and the Rights Agent hereby accepts such appointment. The Rights Agent shall not have any liability for any actions taken, suffered or omitted to be taken in connection with this Agreement, except to the extent of its gross negligence, bad faith or willful or intentional misconduct (each as determined by a final judgment of a court of competent jurisdiction).

3.2. Certain Rights of the Rights Agent. The Rights Agent undertakes to perform such duties and only such duties as are specifically set forth in this Agreement, and no implied covenants or obligations shall be read into this Agreement against the Rights Agent. In addition:

(a) the Rights Agent may rely and shall be protected and held harmless by Parent in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties;

(b) whenever the Rights Agent shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Rights Agent may rely upon an Officer’s Certificate, which certificate shall be full authorization and protection to the Rights Agent, and the Rights Agent shall, in the absence of gross negligence, bad faith or willful or intentional misconduct (each as determined by a final judgment of a court of competent jurisdiction) on its part, incur no liability and be held harmless by Parent for or in respect of any action taken, suffered or omitted to be taken by it under the provisions of this Agreement in reliance upon such certificate;

(c) the Rights Agent may engage and consult with counsel of its selection and the written advice of such counsel or any opinion of counsel shall be full and complete authorization and protection and shall be held harmless by Parent in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

(d) the permissive rights of the Rights Agent to do things enumerated in this Agreement shall not be construed as a duty;

(e) the Rights Agent shall not be required to give any note or surety in respect of the execution of such powers or otherwise in respect of the premises;

(f) the Rights Agent shall not be responsible for any breach by Parent of any covenant or condition contained in this Agreement;

(g) Parent agrees to indemnify the Rights Agent for, and hold the Rights Agent harmless against, any loss, liability, damage, judgement, fine, penalty, claim, demands, suits or expense arising out of or in connection with Rights Agent’s duties under this Agreement, including the reasonable out-of-pocket costs and expenses of counsel in defending Rights Agent against any loss, liability, damage, judgement, fine, penalty, claim, demands, suits or expense, unless such loss has been determined by a court of competent jurisdiction to be a result of Rights Agent’s gross negligence, bad faith or willful or intentional misconduct;

(h) the aggregate liability of the Rights Agent arising in connection with this Agreement, whether in contract, or in tort, or otherwise, is limited to, and shall not exceed the amounts paid or payable hereunder by Parent to the Rights Agent as fees and charges;

(i) Parent agrees (i) to pay the fees and expenses of the Rights Agent in connection with this Agreement agreed upon in writing by the Rights Agent and Parent prior to the date hereof, and (ii) to reimburse the Rights Agent for all Taxes and governmental charges, reasonable out-of-pocket expenses and other charges of any kind and nature incurred by the Rights Agent in the execution of this Agreement (other than Taxes imposed on or measured by the Rights Agent’s net income and franchise or similar Taxes imposed on it (in lieu of net income Taxes)). The Rights Agent shall also be entitled to reimbursement from Parent for all reasonable and necessary out-of-pocket expenses paid or incurred by it in connection with the administration by the Rights Agent of its duties hereunder;

(j) The provisions of this Section 3.2 shall survive the termination of this Agreement, the resignation, replacement or removal of the Rights Agent, and the payment, termination and the expiration of the CVRs.

3.3. Resignation and Removal; Appointment of Successor.

(a) The Rights Agent may resign at any time by giving written notice thereof to Parent specifying a date when such resignation shall take effect, which notice shall be sent at least sixty (60) days prior to the date so specified but in no event shall such resignation become effective until a successor Rights Agent has been appointed and accepted such appointment in accordance with Section 3.4. Parent has the right to remove the Rights Agent at any time by specifying a date when such removal shall take effect but no such removal shall become effective until a successor Rights Agent has been appointed and accepted such appointment in accordance with Section 3.4. Notice of such removal shall be given by Parent to the Rights Agent, which notice shall be sent at least sixty (60) days prior to the date so specified.

(b) If the Rights Agent provides notice of its intent to resign, is removed or becomes incapable of acting, Parent shall, as soon as is reasonably practicable, appoint a qualified successor Rights Agent who shall be a stock transfer agent of national reputation or the corporate trust department of a commercial bank. Notwithstanding the foregoing, if Parent shall fail to make such appointment within a period of sixty (60) days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent, then the incumbent Rights Agent may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. The successor Rights Agent so appointed shall, forthwith upon its acceptance of such appointment in accordance with Section 3.4, become the successor Rights Agent.

(c) Parent shall give notice of each resignation and each removal of a Rights Agent and each appointment of a successor Rights Agent through the facilities of DTC in accordance with DTC’s procedures and/or by mailing written notice of such event by first-class mail to the Holders as their names and addresses appear in the CVR Register. Each notice shall include the name and address of the successor Rights Agent. If Parent fails to send such notice within ten (10) Business Days after acceptance of appointment by a successor Rights Agent, the successor Rights Agent shall cause the notice to be transmitted at the expense of Parent. Failure to give any notice provided for in this Section 3.3, however, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be.

(d) Notwithstanding anything else in this Section 3.3, unless consented to in writing by the Acting Holders, Parent shall not appoint as a successor Rights Agent any Person that is not a stock transfer agent of national reputation or the corporate trust department of a commercial bank.

3.4. Acceptance of Appointment by Successor. Every successor Rights Agent appointed hereunder shall execute, acknowledge and deliver to Parent and to the retiring Rights Agent an instrument accepting such appointment and a counterpart of this Agreement, and thereupon such successor Rights Agent, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Rights Agent. On request of Parent or the successor Rights Agent, the retiring Rights Agent shall execute and deliver an instrument transferring to the successor Rights Agent all the rights, powers, trusts and duties of the retiring Rights Agent.

4. COVENANTS

4.1. List of Holders. Parent shall furnish or cause to be furnished to the Rights Agent, in a form reasonably satisfactory to the Rights Agent, and received from the Paying Agent in the Offer, the Paying Agent in the Merger, and in the case of Holders who held In-the-Money Options and Company Stock Rights, the Company, the names and addresses of the Holders promptly upon the Acceptance Time or the Effective Time, as applicable. Until such list of Holders are furnished to the Rights Agent, the Rights Agent shall have no duties, responsibilities or obligations with respect to such Holders.

4.2. Payment of Milestone Payments. On each Milestone Payment Date for which a Milestone Payment is payable, Parent shall deposit with the Rights Agent, for payment to the Holders in accordance with Section 2.4, the aggregate amount necessary to pay the applicable Milestone Payment to all Holders.

4.3. Books and Records. Parent shall, and shall cause its subsidiaries to, keep true, complete and accurate records in sufficient detail to enable the Holders and their consultants or professional advisors to determine the amounts payable hereunder, including with respect to the amount of Net Sales, Sublicensing Revenue, and Transaction Proceeds.

4.4. Further Assurances. Parent agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered, all such further and other acts, instruments and assurances as may reasonably be required by the Rights Agent for the carrying out or performing by the Rights Agent of the provisions of this Agreement.

4.5. Audit Rights.

(a) Until the termination of this Agreement in accordance with its terms and for a period of six (6) months thereafter, upon reasonable advance written notice from the Acting Holders, Parent shall permit an independent certified public accounting firm of nationally recognized standing selected by such Acting Holders and reasonably acceptable to Parent (the “Independent Accountant”) to have access at reasonable times during normal business hours to the books and records of any Selling Party, as may be reasonably necessary to evaluate and verify Parent’s calculation of the Milestone Payments hereunder, including with respect to the amount of Net Sales, Sublicensing Revenue and Transaction Proceeds; provided that (x) such Acting Holders (and the Independent Accountant) enter into customary confidentiality agreement reasonably satisfactory to Parent with respect to the confidential information of the Selling Parties to be furnished pursuant to this Section 4.5 and (y) such access does not unreasonably interfere with the conduct of the business of the Selling Parties; provided, further, that, for the avoidance of doubt, if an Affiliate of Parent does not meet the definition of a “Selling Party” by virtue of the Affiliate not participating in the invoicing and sales of the Product, then such Affiliate will not be deemed a “Selling Party” for purposes of this Section 4.5(a). The fees charged by such accounting firm shall be borne by the Acting Holders. The Independent Accountant shall provide Parent with a copy of all disclosures made to the Acting Holders. The decision of such Independent Accountant shall be final, conclusive and binding on Parent and the Holders, shall be nonappealable and shall not be subject to further review, absent manifest error. Parent shall not enter into any transaction constituting a Change of Control unless such agreement contains provisions that would permit such Independent Accountant with such access to the records of the other party in such Change of Control if and to the extent as are reasonably necessary to ensure compliance with this Section 4.5. The audit rights set forth in this Section 4.5(a) may not be exercised by the Acting Holders more than once in any given twelve (12) month period. Notwithstanding the foregoing, no audit pursuant to this Section 4.5(a) shall be permitted for any Calendar Year ending on a date more than three years prior to the date of written notice from the Acting Holders of commencement of an audit pursuant to this Section 4.5(a).

(b) If, in accordance with the procedures set forth in Section 4.5(a), the Independent Accountant concludes that any Milestone Payment should have been paid but was not paid when due, Parent shall promptly, and in any event within thirty (30) days of the date the Independent Accountant delivers to Parent the Independent Accountant’s written report, pay each Holder such Milestone Payment (to the extent not paid on a subsequent date), plus interest at the thirty (30) day U.S. dollar “prime rate” effective for the date such payment was due, as reported by Bloomberg, from when such Milestone Payment should have been paid, as applicable, to the date of actual payment, pursuant to Section 2.4(b).

4.6. Commercially Reasonable Efforts. Commencing upon the Closing, and continuing until the earlier of December 31, 2037 or the achievement of all Milestones, Parent shall, and shall cause its Subsidiaries, including the Surviving Corporation, and direct any Sublicensees to, use Commercially Reasonable Efforts to develop and exploit the Product; provided, however; there is no guarantee that Parent will achieve the Milestones. Without limiting the foregoing, neither Parent nor any of its Subsidiaries, including the Surviving Corporation shall act in bad faith for the purpose of avoiding achievement of the Milestones or the payment of any Milestone Payment.

4.7. Progress Report. Within sixty (60) days after the end of each Calendar Year until the earlier of December 31, 2037 or the achievement of all Milestones, Parent shall provide to the Rights Agent a written report summarizing in reasonable detail, and certified as true and correct by an officer of Parent, the activities Parent and its Subsidiaries, including the Surviving Corporation have undertaken in the preceding twelve (12)-month period to develop and exploit the Product (the “Progress Report”). Without limiting the foregoing, Parent shall provide to the Rights Agent an additional Progress Report within sixty (60) days after the 18-month anniversary of the Closing Date. Within sixty (60) days after receipt of a given Progress Report, if the Rights Agent requests a meeting with representatives of Parent to discuss such Progress Report, then Parent shall make available for such a meeting at least one officer with operating responsibility for, and with appropriate expertise and knowledge of, the activities related to the development and exploitation of the Product.

5. AMENDMENTS

(b) Promptly after the execution by Parent and the Rights Agent of any amendment pursuant to the provisions of this Section 5.2, Parent shall mail (or cause the Rights Agent to mail) a notice thereof through the facilities of DTC in accordance with DTC’s procedures and/or by first class mail to the Holders at their addresses as they appear on the CVR Register, setting forth such amendment.

5.3. Execution of Amendments. Prior to executing any amendment permitted by this Section 5, the Rights Agent shall be entitled to receive, and shall be fully protected in relying upon, an opinion of counsel selected by Parent and reasonably acceptable to Rights Agent stating that the execution of such amendment is authorized or permitted by this Agreement.

In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders.

6.3. Successors and Assigns. Parent may assign, in its sole discretion and without the consent of any other Person, any or all of its rights, interests and obligations hereunder to one or more Affiliates of Parent (each, an “Assignee”); provided that each such Assignee agrees to assume and be bound by all of the terms and conditions of this Agreement; provided, further, that Parent shall remain liable for the performance by each such Assignee of all covenants, agreements and obligations of Parent hereunder. This Agreement will be binding upon, inure to the benefit of and be enforceable by Parent’s successors and each Assignee. Each of Parent’s successors and each Assignee shall, by a supplemental contingent consideration payment agreement or other acknowledgement executed and delivered to the Rights Agent, expressly agree to assume and be bound by all of the terms and conditions of this Agreement. This Agreement shall not restrict Parent’s or any successor’s ability to merge or consolidate or enter into or consummate any Change of Control; provided, that in the event of a Change of Control, Parent or the Company, as applicable, shall cause the acquirer to assume Parent’s obligations, duties and covenants under this Agreement. Except as otherwise permitted herein, Parent may not assign this Agreement without the prior written consent of the Acting Holders. Any attempted assignment of this Agreement or any such rights in violation of this Section 6.3 shall be void and of no effect. Unless a successor or assignee meets the requirements set forth in Section 3.3(b), Rights Agent may not assign this Agreement without Parent’s written consent. Any attempted assignment of this Agreement or any such rights in violation of this Section 6.3 shall be void and of no effect.

6.4. No Third Party Beneficiaries. Nothing in this Agreement, express or implied, shall give to any Person (other than the Rights Agent and its permitted successors and assigns, Parent, Parent’s successors and Assignees, and the Holders and the Holders’ successors and assigns pursuant to Permitted Transfers, each of whom is intended to be, and is, a third party beneficiary hereunder) any benefit or any legal or equitable right, remedy or claim under this Agreement or under any covenant or provision herein contained, all such covenants and provisions being for the sole benefit of the Rights Agent and its permitted successors and assigns, Parent, Parent’s successors and Assignees, and the Holders and the Holders’ successors and assigns pursuant to Permitted Transfers. The rights hereunder of Holders and their successors and assigns pursuant to Permitted Transfers are limited to those expressly provided in this Agreement. Notwithstanding anything to the contrary contained herein, any Holder or Holder’s successor or assign pursuant to a Permitted Transfer may at any time agree to renounce, in whole or in part, whether or not for consideration, its rights under this Agreement by written notice to the Rights Agent and Parent, which notice, if given, shall be irrevocable, and Parent may, in its sole discretion, at any time offer consideration to Holders in exchange for their agreement to irrevocably renounce their rights, in whole or in part, hereunder.

6.5. Governing Law; Jurisdiction. This Agreement, the CVRs and all actions arising under or in connection herewith and therewith (whether sounding in contract, tort or otherwise) shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof. Each of the Parties irrevocably agrees that any legal action or proceeding arising out of or relating to this Agreement brought by any Party or its Affiliates against any other Party or its Affiliates shall be brought and determined in the Court of Chancery of the State of Delaware, provided, that if jurisdiction is not then available in the Court of Chancery of the State of Delaware, then any such legal action or proceeding may be brought in any federal court located in the State of Delaware. Each of the Parties hereby irrevocably consent to the jurisdiction of the aforesaid courts for itself and with respect to its property, generally and unconditionally, with regard to any such action or proceeding arising out of or relating to this Agreement and the transactions contemplated hereby. Each of the Parties agrees not to commence any action, suit or proceeding relating thereto except in the courts described above in Delaware, other than actions in any court of competent jurisdiction to enforce any judgment, decree or award rendered by any such court in Delaware as described herein. Each of the Parties further agrees that notice as provided herein shall constitute sufficient service of process and the parties further waive any argument that such service is insufficient. Each of the Parties hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any action or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby, (a) any claim that it is not personally subject to the jurisdiction of the courts in Delaware as described herein for any reason, (b) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (c) that (i) the suit, action or proceeding in any such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

6.6. Waiver of Jury Trial. EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

6.7. Suits by Holders. Except for the rights of the Rights Agent set forth herein, the Acting Holders will have the sole right, on behalf of all Holders, by virtue of or under any provision of this Agreement, to institute any action or proceeding with respect to this Agreement, and no individual Holder or other group of Holders will be entitled to exercise such rights. Notwithstanding the foregoing, in the event of an insolvency proceeding of Parent, individual Holders shall be entitled to assert claims in such insolvency proceeding and take related actions in pursuit of such claims with respect to any payment that may be claimed by or on behalf of Parent or by any creditor of Parent. Notwithstanding any other provision in this Agreement, the right of any Holder of any CVR to receive payment of the amounts that an Entitlement Certificate indicates are payable in respect of such CVR on or after the applicable due date, shall not be impaired or affected without the consent of such Holder.

6.8. Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement shall continue in full force and effect and the application of such provision to other Persons or circumstances shall be interpreted so as reasonably to effect the intent of the parties. The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

6.9. Termination. This Agreement shall be terminated and of no force or effect, the parties hereto shall have no liability hereunder (other than with respect to monies due and owing by Parent to Rights Agent), and no payments shall be required to be made, upon the later to occur of (a) the mailing by the Rights Agent to the address of each Holder as reflected in the CVR Register (or payment by wire transfer, as applicable) the full amount of all Milestone Payments required to be paid under the terms of this Agreement for Milestones that have been achieved on or before December 31, 2037, and (b) December 31, 2037. Notwithstanding the foregoing, no such termination shall affect any rights or obligations accrued prior to the effective date of such termination or Sections 2.4(e), 3.2, 4.5, 6.4 to 6.13, which shall survive the termination of this Agreement, or the resignation, replacement or removal of the Rights Agent.

6.10. Specific Performance. The Parties agree that irreparable damage would occur in the event that the Parties hereto do not perform the provisions of this Agreement in accordance with its terms or otherwise breach such provisions. Accordingly, prior to the termination of this Agreement pursuant to Section 6.9, the Parties acknowledge and agree that each Party shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in the Court of Chancery of the State of Delaware, provided, that if jurisdiction is not then available in the Court of Chancery of the State of Delaware, then in any federal court located in the State of Delaware, this being in addition to any other remedy to which such Party is entitled at law or in equity. Each of the Parties hereby further waives (a) any defense in any action for specific performance that a remedy at law would be adequate and (b) any requirement under any law to post security as a prerequisite to obtaining equitable relief. Notwithstanding the foregoing, the Parties agree that nothing in this Section 6.10 shall require Parent to comply with its obligations set forth in Section 4.6.

6.11. Entire Agreement; Counterparts. As it relates to the Rights Agent, this Agreement constitutes the entire agreement of the parties hereto and supersedes all contemporaneous and prior agreements and understandings, both written and oral, among or between any of the parties hereto, with respect to the subject matter hereof. As between Parent and the Company, this Agreement and the Merger Agreement constitute the entire agreement and supersede all contemporaneous and prior agreements and understandings, both written and oral, among or between any of the Parties, with respect to the subject matter hereof and thereof. If and to the extent that any provision of this Agreement is inconsistent or conflicts with the Merger Agreement, this Agreement shall govern and be controlling. This Agreement may be executed in counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Agreement (including pdf or any electronic signature complying with the U.S. ESIGN Act of 2000, e.g., www.docusign.com) shall be sufficient to bind the parties hereto to the terms and conditions of this Agreement.

6.12. No Fiduciary Obligations. Each of Parent and the Rights Agent acknowledges and agrees that (i) neither party owes any fiduciary duties to the Holders pursuant to this Agreement and (ii) the other party, its Affiliates and their respective officers, directors and controlling Persons do not owe any fiduciary duties to the first party or any of its respective Affiliates, officers, directors or controlling Persons. The only obligations of Parent and the Rights Agent to each other and their Affiliates and their respective officers, directors and controlling Persons arising out of this Agreement are the contractual obligations expressly set forth in this Agreement.

6.13. Confidentiality. The Rights Agent and Parent agree that all books, records, information and data pertaining to the business of the other party, including inter alia, personal, non-public Holder information, which are exchanged or received pursuant to the negotiation or the carrying out of this Agreement, including the fees for services set forth in the attached schedule shall remain confidential, and shall not be voluntarily disclosed to any other person, except as may be required by a valid order of an arbitration panel, court or Governmental Entity of competent jurisdiction or is otherwise required by law or regulation, including SEC or NASDAQ rules and regulations, or pursuant to subpoenas from state or federal government authorities (e.g., in divorce and criminal actions).
